CentOS 7の仮想ホストを作成するbashスクリプト

Question

"ln -s"コマンドで問題に直面していますが、centos 7 HTTPでvhostを作成する次のbashファイルがあります。

（sudo sh vhost.sh create anothersite.com my_dir）「ln -s」という出力が表示されます（/etc/httpd/sites-enabled//etc/httpd/sites-available/anothersite.com）。 .conf）、スクリプトからも分かるように、変数は同じですが、lnコマンドでは2番目の変数だけが表示されます。

のln -sは/ etc/httpdの/サイト利用可能/ $ sitesAvailabledomainの/ etc/httpdの/サイト対応/ $ sitesAvailabledomain

#!/bin/bash 
### Set Language 
TEXTDOMAIN=virtualhost 

### Set default parameters

ここにあなたがあなたの変数$を作成し、ということらしいですsitesAvailabledomain

sitesAvailable='/etc/httpd/sites-available/' 
sitesAvailabledomain=$sitesAvailable$domain.conf 

、それはこの時点で値= '/etc/httpd/sites-available/anothersite.com.conf' を有します。質問から$ 1 $ 2 $ 3の入力を想定します。

そして、ここでは、あなたの変数は、lnコマンドで使用します（これは - 覚えている - 値「/etc/httpd/sites-available/anothersite.com.conf」を持っている）

ln -s /etc/httpd/sites-available/$sitesAvailabledomain /etc/httpd/sites-enabled/$sitesAvailabledomain 

余分なパスで前'/etc/httpd/sites-available//etc/httpd/sites-available/anothersite.com.conf'
